To aZZ whom it may concern:

Be it known that I, SAMUEL BAnUcH, a citizen of the United States, and resident of New York in the county of New .York and State of new and useful Improvements in Antirattling Devices for Vehicles, of which the following isa specification.

This invention relatesto devices adapted to be used in connection with doors, Windows, and other movable parts to prevent.

tect the operating spring which holds the contact member in operative position. The

two members which enclose the spring are permanently connected by simple and inexpensive means, but are ca able of the desired relative movement to e ect the com-- pression or permit the expansion of the spring;

1n the accompanying drawings: I, Fig. 1 is a transverse section showing one positioning of my improved device in comnection with a vehicle door.

Fig. 2 is a; plan view of the device. v Fig. 3 is a central longitudinal section on the line 3-3 of Fig. 2. Fig. l is a section similar to Fig. 1, but

showing the device applied to prevent vertical movement ofthe door.

Fig. 5: isa section similar to Fig. 3, but shewing the device illustrated in Fig. 4.

Fig. 6 is a transversesection on the line 6-6 of Fig. 5.

i Fig. 7 is a transverse section on the line Fig. 8 is a longitudinal section of a further form designed for use with sliding rather than swin ing closures.

In the orm illustrated in Figs. 2 and3,

there is a casing or basemember including a plate portion 10 and a cup-shaped pocket or recess part 11 formed into 211 therewith.

The plate portion 10 may ave apertures therein to receive attaching-screws, and the cup-shaped part 11 is intended to be counew York, have invented certain,

the door cannot rattle.

tersunk below the. plane of the surface to which the plate 10 is attached. In'connoction with this member I provide a second member 12 which is substantially cup-shaped and of an internal diameter slightly less than the internal diameter of the cup part- 11. The cup 12 is provided with a peripheral flange 13 at its open end which may freely slide within the cup 11. The two cups are assembled-with the open end of one Y projecting into the open end of the other so as to entirely conceal and protect a spring 14 within the casin thus produced. For permanently connecting the two cups or casmg sections the open end of the cup 11 is provided with an annular shoulder and a washer or annular ring 15 is placed against this shoulder. The ring extends inward radially substantiallyto the outer surface of the peripheral wall of the cup 12, and is of smaller diameter'than the internal diameter of the flange 13. With the parts thus assembled, a portion of the metal of the face of the plate 10 is forced inwardly so as to form a flange 16 overlying the ring 15 and per.- manently holding the latter in position. This deformation of the metal of the plate 10 may be done by swaging, rolling, or by any suit able form of die.

The device as shown in Figs. 2 and 3 may be inserted in a door casing 17 in such a position'that the door 18 inclosing impacts against'the outer end of the casing section '12 and forces the latter into the casing section 11 to compress the spring 14.. The ordinary catch willhold the door in its closed position, but the pressure of the spring 14 will hold the door to the limit of movement permitted by the catch sothat The outer end wall 19 of the casing section 12 may be slightly I rounded if desired, so that there will be no sharp edges to contact with the door. I t will of course be understood that the dev ce may be mounted in the door to engage with. me the casing, rather than mounted 1n the casing and engage with the door as above described. The spring 14 is preferably of such size and normal length that when the parts are in the position shown in Fig. 3 1 there is practically no outward strampn the casing section 12, and the collar or r1ng 15. The spring may vary in strength according to the charaoter'cf the device with which 1t 1 is tobe employed. a 13.0

If the device is to be employed at the upper or lower edge of a swin 'ng member such as a door, it is referable t at the outer end of the mova le casing section be inclined so as to present a cam surface along which the door may move in reaching final closed position. As shown in Figs. 4 to 7 inclusive, the casing member 12 has its outer end wall presenting an inclined surface 19, and the device is designed to be employed in the upper member of the door casing 17 so that the member 12 has a vertical movement. The door 18*.in closing will strike against the surface 19 and move the latter upwardly as the door rides in until the high point of the surface 19 rests upon and presses downwardly against the upper edge of the door. In this construction it is desirable that the casing member 12 be prevented from rotation. For that purpose the inner surface of the casing section P1 is provided with longitudinal ooves 20, and the flange at the open end of t e casing section 12 is subdivided into a plurality of narrow flange sections or pro:

ections 13' mounted to slide along the firooves 20, as shown particularly in Fig. 7.

y oovin the wall of the casing section 11 and S11 dividing the retaining flange into narrow projections,- the peripheral wall of the casing section 12 may be. made of slightly larger diameter and have free sliding engagement with the inner surface of the casing section 11. The two casing sections serve to enclose the spring 14 and the twocasing sections are connected together by the cpllar 15 and the swaged over flan 16. I

Where it is desired to use the device with a sliding rather than a swinging member, the construction may be substantially as shown in Figs. 2 and 3, and the rounded wall 19 be relied upon to present suflicient anti-friction surface for the sliding member.

The friction may be 'further decreased by providing the contact member with a part having rolling engagement with the sliding member. As shown in I Fig. 8, a casin section 11 may have a roller 19 journale therein-and projecting beyond a slot in the end wall of=the casingso as to engage with a glass panel 18" mounted to slide up and down, as for instance in the upper section of a limousine door. The casing section 11 is held against rotation about its own axis and may be mounted in a main casin section of substantially the form illustratef in Figs. 5, 6' and 7.

From the foregoing it will be seen that my improved device includes only two casing sections, a spring and a retaining .ring. The two casing sections may be of cast brass or other suitable inexpensive material which can be readily swaged over after the as? sembling operation. The' four parts are 1,47o,eea

permanently connected by a single blow of a proper die or by other swaging operation to form the flange 16.

The spring is protected against dust and other foreign materials and the sizes and relative proportions of the arts are such that it is practically impossible for any of them to get out of order. A Thus the device is simple in construction, inexpensive to manufacture, and easy to assemble and is reliable in operation.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. In combination a cup shaped casing member having a plate portion integral therewith at the open end, a ring within said open end and of smaller internal diameter than said casing, a ortion of said casin wall at the open en thereof being swaged over to retain said ring in position, a contact member substantially of cup shape, and having a peripheral flange having sliding engagement within said first mentioned member and retained by said ring and a spring tending to separate said members.

2. An anti-rattling device including a cup shaped member having a shoulder at its open end, a ring within said open end and resting upon said shoulder, and of smaller internal diameter than said casing, an an nular portion of the casing wall at the open end belng swaged over to retain said ring in position, a contact member substantially of cup shape and having a peripheral flange of larger diameter than the internal diameter of said ring, and having sliding engagement within said first mentioned member and retained by said ring and a spring normally tending to hold said flange against the inner surface of said ring.

' 3. An anti-rattling device including a cup shaped casing member provided with a plurality of grooves extending length-wise thereof upon the inner surface, a second cupshaped member mounted to telescope within said first mentioned member and facing in the opposite direction, said second mentioned mem er having a plurality of radially extending projections adapted for sliding engagement in said grooves to prevent relative rotation of said members, a ring secured to the first mentioned member at the open end thereof for limiting the outward movement of. the second mentioned casi member, and a coil s ring enclosed by sai members and norma y tending to hold said projections againstthe inner surface ofsaid r 4. An anti-rattling device including a cup-shaped member, a ring within the 0 en end thereof and of smaller diameter t an said member, a portion of said member being swaged over to retainsaid rin in (mition, a contact member substanti y 0 cup shape5 and having a peripheral flange having sliding engzgement within said first mentioned mem r and retained by said ring, said flange and the inner surface of said first 5 mentioned member having interengagi portions to prevent relative rotation of sai members, and a; spring enclosed by said members and tending to separate them,
